Using Dataslot tab of Subprocess workstep properties
You can use the Dataslots tab to assign and manage dataslots, which control the information flow into and from the Subprocess workstep.
Note: The Dataslots tab is not available for inline subprocesses.
You can add, modify, or remove dataslots assigned to the Subprocess workstep in the Dataslots tab, an easy-to-use interface where you can add new or modify existing dataslots.
By default, the Fields view is displayed, with dataslots listed in a table. The Name column lists the name of the dataslot. The other two columns indicate whether the dataslot is input or output for the subprocess.
To assign a dataslot as input to or output from the Fields view, click in the Input to Sub-Process or Output from Sub-Process column for the dataslot you want to modify, then select true or false in the drop-down list.
